How To Predict The Future Using Excel

Tue 25 August 2009 #misc


I’m going to run out of hard drive space at some point. I’ve got 1.5TB drives in my Drobo right now, I wonder when the 3TB drives will come out so I can just upgrade them in place for double the capacity…

First I looked up when each of the last several capacity jumps were announced. Google news did the trick: 500MB in 2005, 1TB in 2007, 1.5TB in 2008, 2TB in 2009.


Then I plugged my data into Excel and used the ’trend’ formula.


Voila. 3TB is coming out September 3rd, 2012. And that’s about what IDC said.
